Homework Statement
y=x2/3(x2-4)
Homework Equations
The Attempt at a Solution
1.y'=2/3x-1/3(x2-4)+x2/3*2x
2.y'=2x2-8+2x5/2/3(x1/3)
the book agrees with my unsimplified (#1)derivative but it goes further to simplify the equation as
y'= 8x2-8/3(x1/3)
I can't see how they got 2(x2-4)+x2/3*2x to be 8x2-8
in the numerator.
Would someone explain this to me?
